regress
regression coefficients of two variables
Calling Sequence
coefs=regress(x,y)
Arguments
- x,y
real or complex vector
Description
This function computes the regresion coefficients of two
variables x and y, both numerical vectors of
same number of elements n. coefs=[a b] be a
1x2 matrix such that Y=a+bX will be the equation of
the ordinary least square approximation to our data.
